Description
Technical field
This utility model relates to a kind of axial flow blower apparatus field, more specifically, it relates to a kind of armature spindle.
Background technology
Axial flow blower, purposes is widely, it is simply that makes air-flow to the equidirectional movement of the axle of blade, thus reaches conveying easily
Quick-fried, volatile, there is the purpose of corrosive gas or liquid, its general configuration is similar with electric fan, why is referred to as " axial flow
Formula ", it is because gas and is parallel to fan shaft flowing, axial fan is generally used for that traffic requirement is higher and pressure requirements is relatively low
Occasion, axial fan fixed position also makes air move, and axial flow blower is mainly by armature spindle, the impeller that is socketed on armature spindle
Dish, blade, for disposing the case lid of armature spindle, casing to form, axial flow blower is also referred to as TRT.
The Chinese patent of existing Publication No. CN203626892U, by arranging sealing spacer between two impeller disks,
Reaching the further insulation effect of armature spindle and prevent the effect that in gas, armature spindle is washed away by dust, its structure substantially turns
Being provided with two impeller disks on sub-axle, one of them impeller disk is fixed on armature spindle, and another impeller disk is by this impeller disk
Limit with Step Shaft, seal spacer and be arranged between two impeller disks, be fixed on the fixing impeller disk and platform by sealing spacer
Between the axle of rank, seal spacer and make to keep between two impeller disks fixed range.
But, during actual use, due to the high-speed rotation of the impeller disk, seal phase between spacer and two impeller disks
Abrasion mutually, causes sealing spacer and axially shortens along it, seal spacer and can not keep the distance between two impeller disks, impeller disk edge
It axially rocks, and the inner ring of the impeller disk and the lateral wall of armature spindle carry out mutual shock, thus accelerate the damage of armature spindle.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide one to greatly reduce the impeller disk and turn
The armature spindle mutually clashed between sub-axle.
For achieving the above object, this utility model provides following technical scheme:
A kind of armature spindle, including armature spindle body, described armature spindle body is coaxially arranged with the peace for fixing the impeller disk
Dress groove, the sidewall of described installation groove is provided with damping groove, is provided with elastic reaction and leaf in described damping groove
